No.
Accepting proofreading and simple transllation requests will invite more such questions and fast answers instead of discussion to close it, because people like to earn the points.
I guess it is a misconception to catch such users and to turn them into users with more valuable questions. They will not return until they have the next translation request and you will get more questions of that kind.
And different rules for new users and established ones will not work either. Inviting such users to ask such questions at chat is a thing you can do, but I don't know how much reputation you need to join the chat - is reputation from other sections sufficient? I don't think so.
Politics of no broken windows should be our way to go.
Update after adding of examples to the question:
Some have few close votes, some are pretty old, some have already many upvoted answers. I can't see a problem here. However: Keeping poor, simple questions open may lead to many answers and many upvotes. There is no guarantee that the majority of people will keep the number of upvotes down.
